Specification of Letters Intent,

Patented Dec. 2;, 1907.

To all whom 'it may concern:

Be it known that I, Josnrn H. Hnvns, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia 5 and State of Pennsylvania,-ha ve invented certain new and useful Im rovements in Spark-Arresters; and I do dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

This invention relates to s ark arresters, and more particularly to such a device for use upon locomotives, and it has for its ob- {)ect to provide a device whereby s arks wille, revented from issuing from t e smoke stac of the locomotive without interfering with the draft from the fire-box.

Broadly speaking, the device comprises a revolvingscreen .placed at the lower end of thesmoke stack, and a rotary cleaner adaptedto engage therewith and thereby simulta neous] rotate the arrester and remove par- "ticles t at may have beencau'ght and would otherwise obstruct the draft.

In the accompanying drawings, Figure .1 is a broken perspective view of the forward end of a locomotive provided with my improvement; and Fig. 2 is an end elevation of 80 the same.

Referring more articularly to the drawings, 1 indicates t e boiler of a locomotive having the usual smoke box, 2, at its forward end. Journaled in the smokebox,

preferably by means of hangers, 3, and a shaft, 4, 1s a rotary screen, 5.

. A rotary cleaner, 6, isr'nounted adjacent to the screen 5 preferably b being journaled in one of the arms, 7, of t v e hangers, 3, in

.40 position for engaging with the surface of the screen, 5, and thereby rotating the same.

The cleaner is provided with teeth or projections, 8, which are adapted to enter the perforations, 9, in the screen and thereby dislodge any sparks, soot, or other matter that may have collected therein and would have a tendency' to obstruct or interfere with the draft or discharge of the productsof combustion from the smoke box intothe .50 smoke stack. The cleaner can be actuated in any desired manner, as b a flexible shaft,

Application filed August 19. 1907- SorislIo. 886313- driving shown) mechanism of a locomotive Thecleaner is made ofn less I than the smoke box and is preferably placed at a distance from the top, so as to permit of the free circulation of the smoke around it in order for it to pass as freely 88 Po sible through the perforations therein. a his no cessitates the extension of the lower end of the smoke stack 13, down into tho-smoke box, with its lower end preferably ex.- panded recessed it as shown at 14, and-scalloped or sennvcircularly, as shown at 15, i.

so as to correspond'with the curvature of the screen. In this manner, it is impossibio for any sparkto pass from tbe smoke box without engaging with the screen, and

thereby being prevented from passing out of the smoke stack and setting fine to build-' ings or grain along the trac The rotation of the cleaner will nevent the clogging of the screen, whereby t edraft will not be interfered with.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is: 1. In a locomotive provided with a smoke box, a rotary screen ournaled therein, and

a rotary cleaner in engagement with the periphelly of said screen.

2. n a spark arrester, a locomotive pro- Vlded with a smoke box, V-shaped brackets secured therein, a rotary screen journaled in said brackets, a rotary cleaner journaled in two arms of said brackets and provided with means for enga with the screen and thereby cleansing an rotating the same;

3. In a. spark arrestcr, a locomotive pr vided with a smoke box, a smoke stack extending down into said box with its lower end extended and scalloped, brackets in the smoke box, a rotary screen journaled in said brackets with its periphery adjacent to-said eirtended and scalloped portion of the smoke stack, and a rotary cleaner ournaled in position for engaging with the screen and simultaneously rotating 'and' cleaning the same, said cleaner being provided with pro'ections.

4. In a spar 'arrester, a locomotive provided with a smoke box, a smoke stack extending down into the same, having its lower and expanded and scalloped, v V- shaped brackets secured to the wall of the vided with projections for engaging with I smoke box, one of the arms of each of the screen, and means connected with said which is perforated near its upper end, a pulley for rotating said cleaner and screen. shaft journaled inthe lower ends of said a In testimony whereof I have hereunto '3 brackets, a cylindrical screen on said shaft set my hand in presence'of two subscribing 1 Thaw/ ing its periphery adjacent to the lower witnesses.
